Abstract
The utility model discloses a kind of curved arc core-pulling mechanisms of injection mold；Including cover half, dynamic model, oil cylinder, oil cylinder link block, connecting shaft, slide, arc-shaped guide rail, arc core pulling, wedge block；The oil cylinder link block is fixedly mounted on the side wall of dynamic model, the cylinder body of oil cylinder is hinged on oil cylinder link block, the piston rod rod end of oil cylinder and the outer end of connecting shaft connect, the inner end of connecting shaft is hinged on the outer end of slide and the outer end of slide and is abutted against with wedge block, the inner end of slide is connect with the outer end of arc core pulling, slide slips on arc-shaped guide rail, and arc-shaped guide rail is fixedly mounted in dynamic model, and cavity is stretched into the inner end of arc core pulling.Since the utility model cylinder piston rod extracts arc core pulling by slide outward, arc core pulling complies with product radian, and arcuately guiderail track moves so that arc core pulling is fully drawn out disengaging cavity, and final product is ejected by thimble, and then product is taken out, have the advantages that motion stability is reliable.
Description
Technical field
The utility model is related to a kind of injection molds, more particularly to a kind of curved arc core-pulling mechanism of injection mold.
Background technology
Plastics injection mould is the tool for producing plastic products, is widely used general.In plastic products injection molding, by
There is arc endoporus in certain plastic products, need to design a kind of arcuate socket core-pulling mechanism.
Invention content
The purpose of this utility model is to provide a kind of curved arc core pullings of injection mold simple in structure, convenient operating maintenance
Mechanism.
To achieve the above object, the technical solution of the utility model is：
The utility model is a kind of curved arc core-pulling mechanism of injection mold；Including cover half, dynamic model, oil cylinder, oil cylinder link block,
Connecting shaft, slide, arc-shaped guide rail, arc core pulling, wedge block；The cover half is opposite with dynamic model and sets, and wedge block is fixedly mounted
In cover half；The oil cylinder link block is fixedly mounted on the side wall of dynamic model, and the cylinder body of oil cylinder is hinged on oil cylinder link block,
The outer end of the piston rod rod end of oil cylinder and connecting shaft connects, the inner end of connecting shaft be hinged on the outer end of slide and the outer end of slide with
Wedge block abuts against, and the inner end of slide is connect with the outer end of arc core pulling, and slide slips on arc-shaped guide rail, and arc-shaped guide rail fixes peace
In dynamic model, cavity is stretched into the inner end of arc core pulling.
The cylinder body of the oil cylinder is nested with endoporus in bearing by fixing the shaft of its both sides, and bearing is fixedly mounted on oil
In cylinder link block.
After adopting the above scheme, since the utility model includes cover half, dynamic model, oil cylinder, oil cylinder link block, connecting shaft, cunning
Seat, arc-shaped guide rail, arc core pulling, wedge block, when die sinking, cylinder action, cylinder piston rod extracts arc core pulling by slide outward
Son, arc core pulling complies with product radian, and arcuately guiderail track moves so that arc core pulling is fully drawn out disengaging cavity, finally produces
Product are ejected by thimble, and then take out product, have the advantages that motion stability is reliable.The utility model utilizes rail-guided original
Reason, makes the sub- part of arc core pulling be moved along specific track, does compound motion to demould after achieving the effect that product core pulling, has knot
Structure is simple, convenient operating maintenance advantage, efficiently solves the stripping action of product inner core circular arc barb.
The utility model is further described in the following with reference to the drawings and specific embodiments.
Description of the drawings

It is fixedly mounted on the side wall of dynamic model 2, the cylinder body of oil cylinder 3 is hinged on oil cylinder link block 4, the piston rod rod end of oil cylinder 3 and company
The outer end of spindle 5 connects, and the inner end of connecting shaft 5 is hinged on the outer end of slide 6 and the outer end of slide 6 and is abutted against with wedge block 9, slide
6 inner end is connect with the outer end of arc core pulling 8, and slide 6 slips on arc-shaped guide rail 7, and arc-shaped guide rail 7 is fixedly mounted on dynamic model 2
Interior, cavity is stretched into the inner end of arc core pulling 8.
In the present embodiment, the mounting means of oil cylinder is：The cylinder body of the oil cylinder 3 is by fixing the shaft 31 of its both sides
It is nested with the endoporus in bearing 32, bearing 32 is fixedly mounted in oil cylinder link block 4.
The operation principle of the utility model：
When die sinking, oil cylinder 3 acts, and 3 piston rod of oil cylinder extracts arc core pulling 8 outward by slide 6, and arc core pulling 8 is complied with
Arcuately 7 track of guide rail moves 10 radian of product so that arc core pulling 8 is fully drawn out disengaging cavity, and final product 10 is by thimble
Ejection, and then take out product.
The above, only the utility model preferred embodiment, therefore the utility model implementation cannot be limited with this
Range all should still belong to this reality that is, according to equivalent changes and modifications made by present utility model application the scope of the claims and description
In the range of being covered with new patent.
